Although, one problem I see is that legalizing marijuana wont really fix anything. It would just become another gear in the current engine of corruption. It's the systems and the people that run them that are broken and corrupt. Anything you bring into the corrupt system will be just become a part of it, and will be used and abused like everything else. If you want change you need to change the system. What we need is a complete shift away from the way things are running now, but that doesn't seem very likely any time soon.

Legalizing marijuana would probably only mean, in general, that there would be a lot more stone people everywhere, and possibly they'd be even more oblivious to what's going on around them.
